# sphericalHarmonicsLevel

The number of levels of generated spherical harmonics information.

## Declaration

```swift
var sphericalHarmonicsLevel: Int { get }
```

## Discussion

Discussion Each level of spherical harmonics contains more coefficients, and thus affects the layout of the data containing those coefficients. For details, see the sphericalHarmonicsCoefficients property.
